Detailed Description

In order to further disclose the inventive aspects, features and advantages of the present utility model, the following examples are set forth in detail below with reference to the accompanying drawings.

Examples: referring to fig. 1-2, an anti-falling upper sleeve device comprises a manipulator 3 which can move along a linear guide rail 2 under the drive of a telescopic cylinder 1, wherein the maximum stroke of the manipulator 3 in the horizontal direction is 2.4 meters; the telescopic cylinder 1 is arranged in front of the linear guide rail 2, and a piston rod of the telescopic cylinder 1 horizontally extends out and is fixedly arranged on the side face of the swing arm moving frame 5. The upper clamping arm 301 and the lower clamping arm 302 of the manipulator 3 are driven by a connecting rod driving device and a plurality of connecting rods to drive the lower clamping sleeve 4; the sleeve 4 is usually 525mm or 625mm in outer diameter and 700-1400 mm in length. The manipulator 3 is installed at the top of a swing arm moving frame 5, and the bottom of the swing arm moving frame 5 is installed on the linear guide rail 2 through a base 6.

Two upper clamping blocks 3011 attached to the outer surface of the sleeve 4 are arranged at the clamping end of the upper clamping arm 301, and three vacuum chucks 9 are embedded and arranged in each upper clamping block 3011; two lower clamping blocks 3021 attached to the outer surface of the sleeve 4 are mounted at the clamping end of the lower clamping arm 302, and two electromagnetic chucks 11 are mounted in each lower clamping block 3021 in an embedded manner; the vacuum chuck 9 is connected to a vacuum pump 8 through an air introduction pipe 10. The vacuum pump 8 is arranged on the base 6 and fixedly arranged in the middle of the swing arm moving frame 5; the top surface of the vacuum pump 8 is provided with a connecting port connected with a bleed air pipe 10.

The upper clamping block 3011 and the lower clamping block 3021 are made of wear-resistant hard plastic and are respectively fixed on the upper clamping arm 301 and the lower clamping arm 302 through connecting bolts 7. The contact surfaces of the upper clamping block 3011 and the lower clamping block 3021 with the sleeve 4 are provided with anti-skid patterns.

When the width of the upper clamping block 3011 is larger than 350mm, the electromagnetic chuck 11 can be additionally arranged in the upper clamping block 3011, or the upper clamping block 3011 embedded with the electromagnetic chuck 11 can be additionally arranged at the clamping end of the upper clamping arm 301. When the vacuum chuck 9 is additionally arranged on the lower clamping arm 302, the air guide pipe 10 arranged below is easy to interfere with the material platform when the manipulator 3 takes the sleeve 4 from the material platform; and only when the upper clamping arm 301 is provided with the electromagnetic chuck 11 or the vacuum chuck 9, the upper clamping block 3011 has limited specification, so that the electromagnetic chuck 11 or the vacuum chuck 9 has smaller specification, further has limited adsorption force, and still occasionally can be fixed in the operation of a large-specification steel sleeve with the external diameter of 625mm and the length of 1400mm. After repeated testing, it is determined that the electromagnetic chuck 11 must be mounted on the lower clamp block 3021 in consideration of the applicability of the apparatus.
